For those wondering, this seems to be RE: https://news.ycombinator.com/item?id=9861378
If you're using Codecademy you're off to a good start. The question is what do you want to build. A blog? An iOS app? solve some computational questions?
Once you can code, you can work with just about anything because most languages are based on the same fundamentals. So pick a project or a technology and then google "Build a XXX tutorial" or just the technology name and find a tutorial.
I find that the easiest language to learn is Python. Once you know the basics, you can start with http://projecteuler.net for some coding / CS problems. From there move on to https://docs.djangoproject.com/en/1.8/intro/tutorial01/ for some Django stuff.
I tell people to learn languages in this order: Python -> JS -> Java -> C -> C++ -> Haskell/oCaml -> whatever you need for work.
Standard web stacks include LAMP and MEAN. Standard mobile apps are written in Swift (with some C++) and Java (with some other random stuff thrown in there). Pick a set of technologies and write something simple (like a blog or calculator or mini social network.) Then swap out one or two components and build it again. I've built a bunch of blackjack games in 10+ languages with 4 or 5 different UIs, solved a bunch of the projecteuler stuff in a bunch of languages, and at work I play browse around the code base (Java, JS, Coffeescript, Typescript, C++, etc.) to read other people's code. When you do the same project over and over you learn the strengths and weaknesses of each project.
At the end of the day, most tools are mostly the same (especially if you don't have to worry about scale) and their strengths and weaknesses are less important that the developers comfort level.
